According to a Columbia County sheriff's report, Mr. Clements said Mr. Jacobs' van was parked between Mr. Clements' truck and the road. The wrecker pulled forward and back, damaging both vehicles while trying to retrieve the truck.

Mr. Clements said he approached the wrecker to speak to the driver, identified as Mr. Brown.

The wrecker sped forward toward Mr. Clements, according to the police report.

Mr. Clements said he jumped out of the way to avoid being hit. When he turned around, Mr. Clements said, he saw that the wrecker had driven over Mr. Jacobs. The man and woman in the tow truck drove away.

Mr. Jacobs was taken to Doctors Hospital, where he was pronounced dead.

Police issued arrest warrants Saturday charging the Browns with murder. Mr. Brown also is charged with aggravated assault with a motor vehicle, and Mrs. Brown is also charged with battery.
